The PMN-PT is a Relaxor ferroelectric single crystal, we can growth high-quality and large-sized of PMN-PT crystal by using the growth method of Bridgman. It has excellent piezoelectric properties, nonlinear optical properties and pyroelectric properties, PMNT is the core material of a new generation of high-performance piezoelectric transducers, nonlinear optics and photodetector components (such as infrared detectors), Moreover, it also provides a good research carrier for the majority of researchers.
